실험 절차

To a solution of 12.4 g p-tolunitrile in 500 mL of diethyl ether was added 23 g of solid lithium bis(trimethylsilyl)amide at ambient temperature. The mixture was stirred for 2 hours then hydrolysed with 10% HCl at 0° C. The mixture was stirred for an additional 30 minutes and then concentrated to dryness to yield 6 g of 4-methylbenzamidine hydrochloride which was used in the next step without further purification
